RQ2 Math

Column 1

Research Question

How does the the proficiency level in math vary across state for High School Students? Also, how does it vary across the US regions (i.e Midwest, Northeast, South, and West)?

Data Source: https://usafacts.org/

Column

Math Proficiency by Regions

The south region has relatively high percentage of students at and above Math proficiency, in contrast, the West region has relatively low percentage of students at and above Math proficiency. There is no clear pattern for Midwest and Northeast regions as there are large variation of Math profiency within those regions.

Lowerbound Correlation Matrix

The ovals display the type of correlation direction, but there are no significance asterisks included for the correlations.

Initial Full Correlation Matrix

This initial version seems to busy with the large vs. small font sizes and red lines.

Second Full Correlation Matrix

This correlation matrix is missing the lines from the scatterplots, but it is cleaner visually with some overlap in x-axis labels.

Final Full Correlation Matrix

The color is more easily changed via the pairs.panels function.
